I do not understand the question.

I didn't know what aquarenumbers were either BlackNinja,  It is just as well there are mathematics forensic experts amoung us.   Like JonyMyster 

Thanks Alan,

My goodness Nauseated, it seems you have become contaminated very badly with CDD.

You must be hospialised and quarantined immediately.

Do not fret the nurses wear face masks and nose pins so that they can handle the stench!  

Plus it is their calling so they shall nurse you back o health while they struggle to control their nausea.   

Thanks Alan for that great matrix answer.  

I need to have a proper look at all of these solutions.

We have not heard from the anon that asked this question.  I wonder which answer they were after?

NO Definitely not!  

Why would you think that?

Maybe in 3rd grade the bottom was the same all the time.

 Now in 6th grade you are being given harder questions that require more steps.  

Maybe that makes them look completely different.

 But they are really not different.

Thank you.      That is a masterpeice Heureka.   

Unfortunately I do not understand vectors very well so I got lost fairly quickly.

I will try to take time out to understand it better. 

I should  do some study on vectors.  There are just so many things to learn.  

lots and lots
